That's a shame. I kind of wish you had the option to do an OHK execution. There's always a risk when you have to shoot someone from behind that they'll be able to turn around and kill you. It would be nice if there were execution moves for every weapon. What do you guy s think?
They avoided that on purpose.
When you die, you should know why you died, how you died, and that you could have done something about it.
If that isn't the case, then they've failed in their goal.
